E3P23S
Scholium — Part III
Latin
Hæc lætitia vix solida et absque ullo animi conflictu esse potest. Nam (ut statim in propositione 27 hujus ostendam) quatenus rem sibi similem tristitiæ affectu affici imaginatur eatenus contristari debet et contra si eandem lætitia affici imaginetur. Sed hic ad solum odium attendimus.
English (Elwes 1883)
This pleasure can scarcely be felt unalloyed, and without any mental conflict. For (as I am about to show in Prop. xxvii.), in so far as a man conceives that something similar to himself is affected by pain, he will himself be affected in like manner; and he will have the contrary emotion in contrary circumstances. But here we are regarding hatred only.
Modern English
This joy can scarcely be unmixed and free of inner conflict. For (as I will show in P27) in so far as we conceive a thing similar to ourselves to be affected with sadness, we must ourselves be saddened, and conversely when we conceive it affected with joy. But here we are considering hatred alone (E3P27).
